I found out why they say not to cut steel with most blades. It throws hot
chips all over and dulls the blade pretty quick.

Lesson #2: Safety glasses aren't the end-all of safety. A chip found its
way past the glasses and while I'm ok it's a little sore there. I should
have been wearing a full face shield but I didn't have one on site.

Learned something else... Sanders are awesome at deburring steel. I tried
doing it with a file, then switched to the sander and wow what a
difference! Got the piece deburred, rounded, and cleaned in a minute
rather than taking 5 or more with the file.

I've mostly cut metal on my miter saw using a metal cutting wheel. I don't
recall if I ever tried it in a circular but it wouldn't surprised me if I did.

For a railing, I probably would have grabbed my angle grinder with either
a metal grinding wheel or cut-off wheel.

I was going to get rid of my old Delta miter saw when I bought the Bosch
glider, but I decided to save it for cutting crappy wood and metal. Years ago
I had access to a radial arm saw to cut through steel plates up to a 1/2" thick.
Using slow, shallow cuts on a tightly secured plate, you can make some
surprisingly smooth and accurate cuts.
